v JOEL J. HURT, or SOUTH OMAHA,'-NEBRASKA, ASSIGNOR TO EMERSON MANUFACTURING COMPANY, or ROCKFORD, ILLINOIS.

Be it known that I, JOEL J. HURT, a citizen of the United States, residing at South Omaha, in the county of of Nebraska, have invented certain new and useful Improvements plements, of which the This invention has reference ment more tparticularly ada ted for the alfalfa, althoug it possesses features which render'it desirable for the renovation of various other crops. In therenovation of alfalfa it is extremely desirable not only tothoroughly loosen the soil for a suitable depth to admit air, light and moisture, but at the same timeto deloosen up the alfalfa stools s incasing the roots of the alfalfa stalks.

The implement hereinafter more articularly described, is not only ca able 0 breaking' and disintegrating thesoi to a desirable depth without overturning'or otherwise disturbing its strata, but will positively destroy all weeds and loosen up the alfalfa stools,

without destroying the roots of the plants,

thereby materially increasing the yield without in any way injuring the plants. v

For a full description of the invention herein and themerits thereof, and complete knowledge of the details of construction of the preferred means for efiectin these results, reference is had to the fol owing de soription and the drawings hereto attached, in which:

The machine comprises in itsconstruction two sections which are so mounted as to be capable of adjustment, whereby the separate .sections may be arranged at suitable angles with res ect to each other and to the line of draft. herefore', it 1s ,believed that inasmuch as the two sections are identical, the

The work requiredt e one by an implement of this character, demands that the teeth be heavy and strong, inorder that they may penetrate the ground, and as shown, the teeth. have ointed ends 11 to enable them to more easi y enter the ground.

The heads 5 are suitably held in laterally spaced relation on their carrying rods or shafts 4 by means of short s ools 12 which are arranged intermediate eac of the disks 7 comprisingsaid heads, one end of each of saidspools 12 extending through the rings 9 as seen in Fig. 6.

Around the spools 12-whic'h are located or rather disposed intermediate the two outer heads 5 of each of the sections are located boxes preferably made in the form of two half sections 13 and 14,. somewhat as shown at Figs. 1 and 6 and bolted together; this is i also trueofthe central spool 12 of each se ries, seeFig- 1. The upper half sections 14 have "the upwardly extended supports 15, whichmay form a part of or be attached to the said sections, and said supports have secured to their upper ends a weight box orframe 16.

The connection between the bar 1 of the main frame and the ro ds or shafts 4 is through bars 17 connected attheir forward ends to the bar 1 which have their rear ends pivot ally connected to the central sections 14 around the s ools 12 of each of the series, heretofore re erred to as composed of the sections 13 and 14, see Figs. 1 and 5. To theframellare connected bars 18 which extend rearward therefrom and connect with the supports 15 of the central boxes embracingthe central sPQols 12.

The connection just the spools 12 form the fulcrum oint or pivotal connection on which may of the series, for the purpose of changing the angle at which the teeth of the severalheads shall penetrate the soil.

The manner of swinging oroscillatin each section and the series of heads thereo is "as. follows; 19 indicates a hand lever which is pivotally connested to'the pole 2. vA toothed segment 20' is supported on the tongue or pole 2, and the lower end of said lever exboxes 16, as shown at, Fig. 1.

:17 in that their inner ends are connected to the sections 14 of the boxes surrounding the shafts 12 and disposed between the two heads of each of the series of heads, on the inner ends of the rods 4. Thus it will be seen, that upon shifting or throwing the lever 19 through the bars 21, the shafts 4 with their series of heads may be oscillated to assume difierent an les with respect to the line of draft. 'Thelever 19 has a dog.22 adapted to a thumb lever 23 is provided or releasing the dog from the segment. 2 1 is supported by the rear end of the tongue The bars 18 are for the purpose of bracing or holding the support in a vertical position and retainingxthe'weight boxes 16 over the heads 5. o t shaft 4 are attached bumpers 26, seeFigs. '1 and 2. and on the outer opposite ends of said shafts are carried c'ollars 27 and nuts 28 oral heads on the shafts 4:.

Scrapers 29 are provided, cooperating being-secured at their upper endsto bars 30,

tudinal movement to the rear of the weight ends of the said scrapers are curved as at 31 and encircle the spools 12 as shown: and the mediate the collars '27 and the disks 7 as shown.

comprises two shafts 4, each carrying 'aseries of heads 5 arranged in the manner specified on said shafts, andthat the shafts and heads are coupled in such a manner that any movement imparted to one series by the throwing of the hand lever is correspondingly and simultaneously imparted to the opposite series, except that normally the two series of heads are disposed at o posite angles. When transporting the imp ement over-the roads or toy and from a field it is preferable to adjust the shafts 4 at right an les'to the'lineof draft.

n operation, in hard or dry land, the two sections or series of heads are arranged at an angle to eachcther-and to the line of draft by shifting or throwing the hand lever so as to move the inner ends of the shafts 4 rearwardly. In this position each succeeding tooth ofeach head and of the succeeding heads of each section or series will make its own out; intheground, and the out produced ,byone' toothwill not be a continuation of engage the teeth of the toothed se ment 20, an

In wet or loose soil the sections are angled somewhat less than in dry and hard soil, and each tooth will produce a cut as shown in Fig. 9. The reason the sections are angled less for wet soil is, the soil will tear up in greater masses than when the soil isdry and It is not intended to be understood :that cuts will be seenin the-ground as reprehard.

sented at Figs.8 and 9, but these views show the action of the teeth uponthe ground.

By forming the teeth as-if-a continuation of the concavity of the disks 7, a tooth will more readily penetrate into the soil, and the .latter will be stirred and loosened to a C011.

siderable-depth without the least tendency to spading' action on the part of the teeth whereby the roots of the plants would be out. The weight of the implement will ordinaril besu'fficient to force the teeth into the groun but if necessary weights may be pl aced' in the boxes 16 to assist in forcing the teeth into the ground.

The heads are rotated as a team draws the implement forward. The teeth of the' heads gradually enter the ground and will gradu ally come out of the ground, and in so doing,

the soil is stirred and loosened destroying all weeds and split-ting up the alfalfa stools tearing away the dead sprouts from aroundv the roots of the stalks which naturally means'a better yield of alfalfa. This thorough treatment of alfalfa makes it possible to continue the alfalfa year after year and saves the expense of plowing up and reseeding, which has.

been found necessary in many sections after four or five years continuous crops.

As the teeth of the headsin their movement over a field will pickup trash and clods, the scrapers will clean the same as the heads rotate, and discharge said trash and clods to the rear of thesaid heads. i

In using the term tongue it is understood that a stub tongue can be employed to which is connected a truck, without departing from the scope of my invention;

At Fig. 10 I have shown two hand levers for moving the sections and it is immaterial whether one or two hand levers are employed, as I intend my. claims to cover both constructions.

Iam aware that there have been made disk harrows as well as "plowing machines wherein the .disks as well as the rotary-shares have been arranged in two gangs and so coupled that they could be simultaneously thrown at an angle to each other and to the line of draft, except as to such ad justment there is no similarity of construction or operation between. those devices and 4 nary plow obviously therefore the disk-harrow or the low using rotary plowshares is essentially ifferentfrom the implement constitutingthe present invention.

I am further aware of the use of spadingdisks or blades similar to those used in cultivators, but so far as I know they are so mounted asto rotate independently about their axial supports and do not sustain the frame-work of the machine, whereas in my improved implement the toothed heads carry the frame, rotate in unison and rotate their shafts. Furthermore the useof a spading-disk or'blades in working alfalfa would inevitably cut the roots of the plants,.and thus eifectserious injury which cannot occur in the operation of my implement. It is also true that blades of the character just described throw the earth away in a-furrow, while my only aim is-to penetrate the soil to a considerable depth for the purpose of breaking, loosening and 'disinte ratin the same without injuring the roots 0? the p ants.

I am further aware that disk-harrows have. been used, wherein each disk had a cutting edge formed with a series of .teeth, projecting alternately in opposite directions from the plane of the disk. Such harrows on: account of the cutting edges of the disks are wholly unsuited to properly renovate alfalfa, a peculiar type of machine being needed for that purpose, and, my present machine having been constructed with especial reference to the conditions of that partioularduty.

It has been proposed to use diggers and plows of various types, disks having teeth free to move to a certain extent with relation to the. disks, a constructions differing from mine and objectionable for obvious reasons; and it has also been proposed to use scrapers as combinations with rotary diggers, none of the devices of the prior art show the combination, of elements herein described and claimed, nor do any of them meet the require ments of the peculiar service to which my implement is adapted, and for which it has been especially devised. I claim as my invention. 1. An implement of. the character de-. scribed comprising a 'tongue, two .approXi 'mately horizontal shafts pivoted withrelation to the tongue and adjustable about their pivots, a'series ofspike-toothedheads, suitably retained in spaced relation .on-each of said shafts, and in operation adapted to penetrate and loosen the ground, and hand lever means for varying the angular relations of the shafts to the line of draft and holdin them in theindifl'ercntpositions.
